In order to adapt to and promote the development of the industry, urban rail has been born as a new mode of transportation. Correspondingly, new requirements have been put forward for the safety of urban vehicle operation and maintenance. In order to ensure the safety of vehicle operation, vehicles need to be lubricated regularly.

[0003] In the maintenance of EMUs, the existing filling method relies on manual work with simple tools (e.g., measuring cups, oil pots, etc.) to fill the gearbox oil. The existing working method has the following defects:

[0004] (1) Oil products are collected manually, and the type and quantity of oil collected are unknown and unrecorded.

[0005] The collection of oil products is completely dependent on manual collection, and the collection amount and type are unknown. The efficiency of manual oil collection is too low, and accidents are prone to occur, resulting in oil spillage and other situations.

[0006] (2) Low work efficiency. During the entire maintenance and filling process, all work is manually controlled and recorded, resulting in long working hours, high work intensity, and low work efficiency.

[0007] (3) The filling data has no accuracy, and the data cannot be queried and traced. During the filling process, the amount of oil added is determined by manual observation of the oil level. There is no data on the filling amount, and the filling accuracy cannot be controlled. The data after filling is recorded manually, and all the filling information cannot be searched or traced.

[0008] (4) The existing filling equipment has a complicated filling process and cumbersome operation. The existing filling equipment fills different types of oil separately, with different filling processes and different filling precisions. The process is complicated and the working methods of each device are different, making the operation complicated and cumbersome. Summary of the invention
